Definitions

  • the present invention relates to a rolling mill and, more particularly, to a construction that enables the rapid replacement of certain components of the mill.
  • Another feature to which the present invention has reference is to the removing and replacing of the filler blocks provided between the lower roll chock and the housing of a mill having two or more rolls, which filler blocks compensate for the difference in diameters of the rolls employed in the mill.
  • the mill is designed to receive rolls of varying diameters which in one 4high mill by way of an example, the work rolls varied from 20" minimum to 23" maximum and, with respect to the backup rolls, their diameters varied from 50* minimum to 56" maximum.
  • the present invention provides an improved means for quickly and mechanically removing and replacing the filler blocks so that the mill will not be held out of service for any appreciable length of time.
  • Both of the aforesaid objects are accomplished by providing at the base of the mill, say for example a 4-high mill, means for raising the lower backup roll and both work rolls in a direction away from the base of the ice housing, whereby the lower backup roll chocks are freed from the filler blocks, including means for quickly removing the filler blocks out from under the chocks so that the roll assemblies can be lowered, in which connection the work roll assembly will be also lowered so that a portion will coincide with the elevation of the platform in front of the mill.
  • the filler blocks they can be conveniently removed and replaced by others.
  • FIGURE 2 is a view similar to FIGURE 1, showing the filler block removed from under the backup roll and the rolls in their lowered positions;
  • FIGURE 3 is a sectional view taken on lines IIIIII of FIGURE 1, showing more fully one of the filler blocks and assorted components in their operative positions;
  • FIGURE 4 is a sectional view taken on lines IVIV of FIGURE 2, showing more fully one of the filler blocks in its inoperative or withdrawn position.
  • FIGURE 1 there is shown one of the two identical component housings, in which the component of one housing 11 will be referred to only.
  • the housing 11 has a window 12 into which is received four rolls to make up a 4-high mill, i.e., the work rolls 13 and 14 and backup rolls 15 and 16.
  • the work roll 13 is received 'in a bearing-chock assembly 17 which has two downwardly extending legs 18 that form a recess 19 into which is received the bearing-chock assembly 21 of the lower work roll 14.
  • the chock 21 is held in the chock 17 by latches, not shown. At the very bottom of the legs of the chock 17 wheels are rotatably mounted.
  • the backup rolls 15 and 16 are likewise provided with bearing-chock assemblies, the backup roll 15 having a bearing-chock assembly 22, which at its lower portion has opposed downwardly extending positions 23, the ends of which take the form of 'a hook 24 which engages in certain instances cooperative projections 25 formed on the upper port-ion of the bearingchock assembly 17 of the upper work roll 13.
  • the sled 34 has two parallel spaced-apart rails 35 and 36 which fit inside the window 12 of the housing 11.
  • the backup chock 26 of the lower backup roll 16 is not in engagement with the rails 35 and 36 so that, as previously explained, the rolling pressures pass from the chocks into the housing 11 via the fillers 29 and pressure block 31.
  • the top surface of cut-away portion 27 formed in the chock 26, however, upon the removal of the tiller block 29 is adapted to come into engagement with the rails 35 and 36 whereby the chock 26 is carried by the rails of the sled 34.
  • the filler block 29 is received in the retractable platform 30 which, in turn, is received on the sled 34 and movable relative thereto wherein it slides over spaced-apart bushings 42.
  • These bushings shown only in FIGURE 1 take the form of inverted L shaped members which are carried by the rails 35 and 36 of the sled and wherein the upper portion of the bushings overhang the platform 30 and thus restrain it in the vertical direction.
  • the piston cylinder assembly is carried on the base member 34A of the sled 34 and secured thereto by a bracket shown only in FIGURE 1. Upon operation of the piston cylinder assembly 45, once the lower chock 26 has been raised, the filler block 29 will be moved from the position shown in FIGURE 3 to the position shown in FIGURE 4.
  • FIGURE 2 there is one other element of the mill that needs to be described which is the roll balance assembly for the upper backup roll 12.
  • the roll balance assembly for the upper backup roll 12 As shown in FIGURE 2, there is provided at the top of the chock 22, arms 46 which engage projection 47 formed on the chock 22, the arms 46 being connected to a double-acting piston cylinder assembly 48 which, in turn, is carried by the separators that extend between the mill housings.
  • the operation of the piston cylinder assembly 48 in one direction raises the chock 22 and the projections 24 engage with the projections 25 of the upper work roll chock 17, whereby the cylinder 48 i will carry the weight of the upper backup roll 15 and work rolls 13 and 14.
  • the piston cylinder assembly 45 is operated to remove the filler block 29 out from under the chock 26 to the position shown in FIG- URE 4. Following this, the piston cylinder assembly 37 will be lowered to lower backup roll 16. The lower position of the chock 26 of the backup roll 16 will bring it into a supporting relationship with the rails 35 and 36 of the sled 34. Assuming that the work rolls 13 and 14 are to be changed, the piston cylinder assembly 48 will be operated to allow the rolls 13, 14 and 15 to be lowered to the position shown in FIGURE 2 which presents the lower surface of the wheels 20 of the upper work roll chock 17 at the same elevation as the fioor.
  • the present invention is equally advantageous for use with a roll balance cylinder arrangement wherein the cylinders thereof are inserted into the legs of the backup chocks, and wherein the work roll chocks are nested in the backup chocks.
  • the cylinders 37 and 38 lift the entire complement of rolls and then lower them onto stops.
  • the present invention is applicable to a mill which employs a backup roll changing rig connected to two rails which after the ChOcks are raised the two rails are inserted into the mill under the bottom backup chocks and carry the rails after they have been lowered thereon to a position outside of the mill, all according to well-known practice.
  • a housing having a vertically arranged window for receiving a pair of rolls
  • a retractable carriage for receiving said filler blocks and for moving said blocks into and out of a position under said bearing chock assemblies of said lowermost roll, a sled mounted in said window and below said lowermost roll and constructed to support said carriage,
  • bearing chock assemblies of said lowermost roll having spaced-apart recesses in the areas adjacent to said rail and between said recesses, a projecting portion adapted to be engaged by said filler blocks, and
  • said recesses being such that during operation of the mill the filler blOcks maintain said bearing chock assemblies of said lowermost rolls out of engagement with said rails and on retraction of said filler blocks allow the bearing chock assemblies of the lowermost rolls to be lowered into engagement with said rails.
  • a housing having a vertical window for receiving a pair of working rolls and a pair of backup rolls
  • the working rolls having an operative position and a roll changing position which is below the operative position of the working rolls
  • a sled extending to said window and constructed to carry said filler blocks in a manner that rolling pressures of the mill are taken solely through the filler blocks into the housing
  • said sled including surfaces for carrying the bearing chock assembly of the lower backup roll
  • said surfaces being formed to allow said working rolls to be lowered to the roll changing position
  • the upper portion of the bearing chock assembly of said lower backup roll being constructed so as to allow the adjacent working roll to move axially Without contacting the bearing chock assembly of the lower backup roll.
